Product Details
This small blind ultrasonic level meter was developed by Aumeascon is a non-contact level measuring device characterized by an ultra-short blind zone only 10cm and reoslution: 1mm, enabling precise measurements even for small containers or when the liquid level is close to the sensor installation position. It works on the time-of-flight principle, using ultrasonic pulses to calculate the liquid level. and it’s with different output: RS485 Modbus, 4-20mA and configurable settings for stable data. Widely used in industries like chemical engineering, water treatment, and food processing, it is suitable for measuring various liquids and some solids.
Technical Specification
